I think I may have lost a spring. Took the boat out today and everytime I pull the choke knob, it springs right back to the open position. There must be a spring to help hold it closed. If anyone has a close-up pic of the back of their briggs could you please post it or if you know the part # that would be even better. I tried looking at the parts catalog on line, but didn't see exactly what I was lookin for. Thanks.

Here's what I've got now. Kind of a crappy pic but it's hard to get that close-up. This is from the starboard side looking back behind the carb.

Looks like you are missing the choke return spring. PM me your address and I will send you one.
